External Trigger (Trig In)
The external trigger input can be used to trigger a sequence. The
schematic below shows the input schematic of the input.
Figure 4: Trigger Input, schematical presentation
Please look at the Appendix for detailed technical specification.
External TTL
Allows to use a TTL signal at the BNC connector of the trigger input. The
trigger is rising edge sensitive.
External Switch
Allows to use an external switch, a TTL signal or an open collector to
trigger the sequence. The trigger signal is falling edge sensitive which
means, that e.g. the switch has to be closed to trigger the sequence.
Trigger Control-LED
The Trigger Control-LED shows, if a trigger signal has been detected by
the camera. In this case, the LED goes on for about one second.
External Synchronisation Input (Sync In)
The camera allows to be externally synchronized by an external pulse
generator to frame rates, which are not given by the internal frame rates of
the camera. To do this, a TTL signal has to be applied to the external
synchronisation input. The camera detects the rising edge of the signal.
